The following video represents an example of HMI in Industrial applications. In particular, in this project I used an Android multi touch that runs on Cortex A8 at 1Ghz and show how it can greatly control an AC drive. Specifically, I used a Allen-Bradley adjustable frequency AC drive.

The Android UI on the touch screen device allows to:

• Start/Stop the motor
• Set the direction (forward, backward)
• Manage the output relay
• Control the status of the digital inputs
• See the parameters such as the current, frequency and output voltage
• Set the motor frequency

You’ll find the source code and complete specifications of the project on my github channel. Don’t miss to check it out also our wiki section! As usual, comments are welcome 🙂
